Yep, but no pics handy at the moment. I used the Autoleads conversion kit. Some of the guys got genuine Toyota ones. I think I might get one myself when I get the urge to rip it all out again as the Autoleads one comes in several parts which tend to come loose over time.
I brought the power cable through the grommit just under the battery to the passenger-side footwell. The Lexus owners club and Australian Tezzaworld forums have good pictorial guides on how to do it.
